My input is linked to a property on scope:
<input type="text" ng-model="folderName">
$scope.folderName = ""
If the input has a value, folderName will be equal to that string. However, if I clear the input, folderName becomes undefined instead of an empty string. Is this behavior normal?
When using validation such as required, if the textbox is invalid because it does not have a value, then it will be considered as undefined. This is why you are seeing undefined.
If you remove the required attribute and check the value, it should no longer be undefined.
This behavior is handled by angular so there is no need to worry about it.
